Thanjavur Marathi (colloquially called Rayar)), are a Marathi-speaking ethno-linguistic group, who reside in the central and northern parts of the Indian state of Tamil Nadu. They are the descendants of Marathi administrators, soldiers and noblemen who migrated during the rule of the Thanjavur Maratha kingdom. Thanjavur was a Maratha kingdom in Tamil Country, until the British dethroned the last Thanjavur Maratha king. It was founded by Maratha Warrior Chatrapati Shivaji's brother, Venkoji Rajē Bhonsalē. Kshatriyas use the designation Maratha while Brahmins use the self-designation Deshastha.
